concern:

Be it known t at I, BERNICE J. None, a citizen of'the United States, residing at Boston, in the county of Suffolk and-State of Massachusetts, have invented unlmprovement in Electric-Lighting Systems for Automobiles, of which the following is'a speci: fication.

Electric lighting systems ordinarily used on automobiles are provided ,with 'a switch arranged near-the drivers' seat by which the lamp-circuifl'is closed and opened t0. turn on and off thelampsat will. In view of the advantage taken ofthyis' convenience by unscrupulous persons who suddenly turn off the lamps, and drivfe ofi unobserved, considerable objection is raised to the employment of such a system.

This invention has for its object-the construction of controlling-means for an electrio lamp-circuit of this desc'riptiom-which involves the employment of a swltc ranged near the drivers seat adapted to be operated to-turn on the lamps, an'd' which, when thusoperated is held against return movement, and means controlling the return movement of' the switch to :riormal, which is arranged for operation at the rear 01' front or some other part of the automoliil remote frpm thediivefls seat, and WhlC'l necessitatesithedriver stopping the automo bile and ge'ttingout to turn out the lamps.

The invention also has-to us ohj ect the provision of mins 'for dimming the'lump's adapted to'be operated. by-the switch move.- ment of the switchqriiiiber for ii'ccornplishing this result hothe irjg obstructed that mobile having an.electriclighting system' embodying this invention.

Fig. 3 is a side view and partial vertical section of the parts shown in Fig, 2.

Fig. 4 is a sectional view of the circuitcloser for the controlling-device of the lampcircuit which is located at a. "remote point.

Fig. 5 is a plan view of a conduit system for the circuit-wires of the lamp-circuit by wh ch they are concealed.

Fig. 6 is a diagram of the circuit,

Said switch arm normally rests against a stop-pin 19" and is";no rmully so-held by a spring. 25 which ,is attached to it, but when moved to ,cl'ose the'cii-cuit said, spring is elttended and subsequently acts, when ermltted, to retupn the -.switcl'1-a1?m. t-nid swltch-armfis-movable-iutoengagementwith a Q, n9 :m mber 22, wh ch. is con e through ares.

Bymeans of this conduit-system the 'circuifiwires are entirely inclosed', so that they cannot be tampered-with, particularly It will, therefore, be observed that the switch-for'turning on the lamps is arranged in the car and is easily accessible, whereas theswitchfor turning off the lam 's is 015- erated by mcans'on the outside of t a car.
